Dear Sir, I am making a program using Keil PK51 package. I am using a structure of arrays declared as: #define MAX_TESTS 30 struct param{ /* 80 bytes per test */ char mode[MAX_TESTS]; float factor[MAX_TESTS]; int aspVolume[MAX_TESTS]; char temperature[MAX_TESTS]; char filter1[MAX_TESTS]; char filter2[MAX_TESTS]; char unit[MAX_TESTS]; float nvMin[MAX_TESTS]; float nvMax[MAX_TESTS]; char decimal[MAX_TESTS]; int reagVolume[MAX_TESTS]; int sampleVolume[MAX_TESTS]; float linLim[MAX_TESTS]; float blankMin[MAX_TESTS]; float blankMax[MAX_TESTS]; int delayT[MAX_TESTS]; int rateT[MAX_TESTS]; char noOfReadings[MAX_TESTS]; float absMin[MAX_TESTS]; char printCurve[MAX_TESTS]; char shortName[MAX_TESTS][SHORTNAMELENGTH+1];/* +1 is for NULL Character */ char fullName[MAX_TESTS][FULLNAMELENGTH+1];/* +1 is for NULL Character */ float standard[MAX_TESTS]; float blankOD[MAX_TESTS]; float standardOD[MAX_TESTS]; unsigned char DACgainSet[MAX_TESTS][2]; unsigned char calibrationDone[MAX_TESTS]; unsigned char relayStatus[MAX_TESTS][2]; }; struct param xdata saveTestParam _at_ 0x8000; I want to initialise these 30 tests with some initial values which are different for different tests. One set of structure takes 80 bytes of storage so for 30 tests, 80x30 = 2400 bytes are required. I would like to store all these values(which are different for different tests) in the code memory and use a for loop to initialise these tests. I am not sure how to store these values in the code memory so that they can be transferred to the structure whenever required. Can anyone guide me how to do this. I am using a Keil C cross compiler. Regards, Mohit
